Illustrative Mathematics: 5.nf Grass Seedlings

Curated by ACT

For the sake of this commentary, let R be the height of Rual's seedlings (of course students do not need to use a letter to represent any number in this task). Student must compare the size of each of two products (112xR, and 34xR) to one factor (R) on the basis of the other factor without performing any computations. Aligns with 5.NF.B.5.
